 /**
  * <p>
  * This is an extension to the standard ISiteFactory interface.
  * If a factory implements this interface and is handling
  * URL connections, a progress monitor can be passed to
  * allow canceling of frozen connections.
  * </p>
  * <p>Input stream is obtained from the connection on
  * a separate thread. When connection is canceled,
  * the thread is still active. It is allowed to terminate
  * when the connection times out on its own.
  * </p>
  * <p>
  * <b>Note:</b> This class/interface is part of an interim API that is still under development and expected to
  * change significantly before reaching stability. It is being made available at this early stage to solicit feedback
  * from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
  * (repeatedly) as the API evolves.
